Johnnie Troutman knows he needs to step his game up -- or someone else will in his right guard spot.

The 6-foot-4 right guard left Philip Rivers out to dry one too many times in pass protection last season, according to Pro Football Focus. And with the influx of new Chargers blockers, he'll need to prove he's starting material all over again.

"You have competition every year," Troutman told ESPN. "They want to get better at every position, so every year they bring someone in to try and take your job."

The former Penn State product is ready to welcome all challengers. The banged-up knees that sidelined him for Weeks 16 and 17 last season are no longer an issue. Plus, Troutman has trimmed eight pounds off his frame in an attempt to gain an edge.

Every little bit helps. This summer, former Rams tackle Joe Barksdale and second-year pro Jeremiah Sirles are just two names gunning for his job.

Said Troutman: "I'm feeling good. Both knees are good health, and I'm ready to go."
